BIOS for the Gigabyte GA-H81M-D3V motherboard, an Intel H81 micro-ATX board, supplied as a ZIP of about 3.20 MB. No version number or board revision appears in the name, so look inside for release notes and compare against the revision marked on your PCB.

When programming the SPI flash externally, read and keep the original contents, and confirm the image size equals the chip capacity before writing.
